Abstract

This paper considers the application of magnetorheological (MR) damper, RD-8040-1, for attenuation vibration in flexible truss bridge deck structures. The modeling and identification of the damper property by using SAP2000 analysis software from an experimental data set generated by dynamic tests of the MR damper mounted in a testing machine where velocity and current are used as input, and the force as output. Theoretical investigations and in-site experiments are carried out in Chamran’s laboratory, Ahvaz, Iran. Truss bridges are an innovative structure that shall be studied in their systems and connections to earn stability and damping in related to certain lateral loads such as seismic load's post-earthquake load. The issue of damping is the cooperation between elements in the truss bridge of deck systems. Significantly, MR damper among components based on their reaction can be defined in the form of a percentage of control of loads in the structure of deck in a bridge system. This article proposes the application of damper at interconnecting of bridge deck through minimizing vibration force by using the Bouc-wen model. In summary, this paper is understood the effect of damping application on overall formation nonlinear analysis Models at this major element.
